Let’s dive in!

✅ What Are Comment Backlinks?

Comment backlinks are links that you leave in the comment section of blog posts, forums, or article discussions. Usually, they appear as part of your name, website field, or within the comment text itself.

For example:

Great insights! I also wrote a guide on [Your Blog Name] about this here – [yourwebsite.com/post]

These links are typically nofollow, meaning they don’t pass link juice directly. But that doesn’t mean they’re useless. Here’s why…

💡 Why Comment Backlinks Still Matter in 2025

Despite being nofollow, comment backlinks can still offer SEO benefits:

📌 1. Indexing Support

If you’re launching a new blog or webpage, comment backlinks from indexed sites can help Google discover and crawl your content faster.

🌐 2. Referral Traffic

Well-placed comments on high-traffic blogs can bring targeted visitors to your site.

🎯 3. Diversity in Backlink Profile

Google wants to see a natural backlink profile. Comment backlinks provide diversity and show your link-building isn’t artificial.

🛡️ 4. Brand Visibility

Frequent commenting on niche blogs builds awareness and credibility in your industry.

⚠️ Common Mistakes to Avoid

Before we explore the “how-to,” here’s what NOT to do:

❌ Don’t spam the same message on every site
❌ Don’t use exact-match keywords in the name field (e.g., “Best Digital Marketing Agency”)
❌ Don’t comment on irrelevant or low-authority blogs
❌ Avoid sites with thousands of spammy outbound links

🛠️ How to Create High-Quality Comment Backlinks (Step-by-Step)

Here’s how to get the most value out of your comments:

Step 1: Find Relevant Blogs

Search Google with keywords like:

• “Your niche + leave a comment”
• “Your topic + powered by WordPress”
• “Your topic + commentluv enabled blogs”

You can also use advanced search operators:

intitle:"leave a comment" "digital marketing"
inurl:/blog/ "seo tips"

Step 2: Read the Blog Post First

Don’t just skim — actually read the article. Your comment should show genuine interest.

Step 3: Add Value in the Comment

Write at least 2-4 sentences. Add a point, share your experience, or ask a question.

Example:

“This post was incredibly helpful, especially your point about on-page SEO. I’ve been experimenting with schema markup too, and I noticed a jump in CTR. Would love to hear your thoughts on that.”

Step 4: Use Your Real Name

Avoid spammy names like “Cheap Backlinks Provider.” Use your name or brand.

Step 5: Insert a Natural Link (If Allowed)

If it fits the context and the blog allows it, link back to your relevant article.

🔎 DoFollow vs. NoFollow Comment Backlinks

Most blog platforms (WordPress, Blogger, etc.) default to nofollow for comment sections to prevent spam. But some blogs and platforms still pass dofollow juice.

Look for blogs with:

• CommentLuv plugin
• Custom settings that allow dofollow
• Moderated communities with manual approval

Tools like SEOQuake or browser extensions like NoFollow Checker help you identify them.
